21.16. The Optionmenu Widget
Use the Optionmenu method to create an option menu, in which the selected item is the value displayed. For example:
$mainwindow->OptionMenu(-textvariable => \$platform,
-options => [ [ "UNIX", "unix" ],
[ "Windows NT", "winnt" ],
[ "Macintosh", "mac" ] ]) -> pack;The -options argument takes a list of menu items. If the descriptions of the menu items displayed are different from those of the values stored, the menu items are themselves written as two-item lists.
The standard configuration options that apply to Optionmenu are: -activeback-ground, -activeforeground, -background, -bg, -bitmap, -borderwidth, -bw, -cursor, -disabledforeground, -font, -foreground, -fg, -highlightbackground, -highlight-color, -highlightthickness, -image, -justify, -relief, -state, -takefocus, -un-derline, -width, and -wraplength.
Other options are:
- -command => callback
- The command to execute when a selection is made. Its arguments are the values of the -textvariable and -variable options.
- -indicatoron => boolean
- Determines whether to display an indicator.
- -menu => $menu
- Displays the menu associated with $menu.
- -options => list
- Lists the menu options, as described above.
- -tearoff => boolean
- Whether to allow the menu to be "torn off." Default is 1.
- -text => string
- Specifies the text to display as a label for the option menu.
- -textvariable => \$variable
- Points to the variable containing text to be displayed in the option menu.
- -variable => \$variable
- Points to a variable containing a stored value, distinct from the value shown in the option menu.
